RADIATOR VENT VALVE. APPLICATION FILED MAR.14, 191s.

Patented Oct. 7,1913.

awe/W601,

UNITED sTA'rE PATENT OFFICE it JACKSON, OF CHICAGO, ILLINOIS? To all whom it may concern:

. clogging and Be it known that I, ANDREW Jackson, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Radiator Vent- Valves, of which the following is a specification.

This invention relates to vents for permitting the escape of air from radiators when steam is turned into the same.

I It is the object of the present invention to provide in a device of this kind a mulfier which permits the air to escape without noise, and which prevents hissing of escaping steam.

A further object of the invention is to provide novel and improved means whereby flooding of the vent is prevented.

The invention is illustrated in the accompanying drawing forming a part of this specification, in which drawing,

. having a reduced externally screw-threaded lower end on which is screwed a mufiler' which shoulder and the upper end of the tube 11'is placed a packing 15 to prevent leaka e. This packing is located in the neck and forms a tight closure for the same. The m'ufller tube 11 is bent into the form of a, trap. As shown, the tube extends to the bottom of the shell 5 where the bend is made, and it then extends upward and terminates nearthe top of the shell.

. mm'ron VENT-VALVE,

Patented Oct. 7, 1913.

The tube is filled with disks 17 of fine metal gauze, which are placed close together one above the other. In one portion of the tube an oily rag 18 is substituted for some of the gauze disks.

In operation, the steam entering the shell- 5 at the bottom rises and enters the upper end of the upward bend of the tube 11 and then slowly works its way through the gauze fragments 17 so that its pressure is constantly reduced. Upon passing through the rag 18, the steam is sufficiently bafiied and it passes out of the vent without noise. Varying degrees of heat may be obtained by regulating the needle valve 14 by means of the cap 8, so that the circulation or steam in the radiator is hastened or retarded. The valve may also be entirely closed.

. It will be seen that clogging of the tube 11 will be prevented becauseall solid particles in the steam settle to the bottom of the shell 5 as the steam passes upward to the entrance end of the tube. Flooding'is prevented because if the shell should fill with water, the same will not pass the mufliing m'eans inclosed in the tube, and the packing 15 prevents leakage at the neck 7. Ordinarily, the water will not rise in the shell to the height of the inlet of the tube.

In the modified form of mufiler tube shown in Fig. 2, the lower end thereof, at the bend, has a coil 16, and in the modified form of muiller tube shown in Fig. 3, the upward bend is coiled around the depending portion of the tube as indicated at 19.

I claim:

1. A radiator vent comprisinga shell having an inlet and a valve controlled outlet, a bent tube located in the shell and connected to the outlet, the inlet end of the tube being at the top of the shell from which it extends downward and then upward to the aforesaid outlet.

2. A radiator vent comprising a shell having aninlet and a valve controlled outlet, a bent tube located in the shell and connected to the outlet, the inlet end of the tube being at the top of the shell from which it extends downward and then up ward to the aforesaid outlet, and muffllng means in the tube.

3. A radiator went comprising a shell having a bottom inlet and a top neck, a plug .seating in the neck and having an outlet channel and a valve seat therefor, a cap closing the neck, said cap having an outlet and carrying a valve for the seat, and a bent tube in the shell and connected to the outlet channel of the plug.

4. A radiatorvent comprising a shell having'a bottom inlet and a top neck, a plug seating in the neck and having an outlet channel and a valve seat therefor, a cap closing the neck, said cap having an outlet and carrying a valve for'the seat, a bent tube in the shell and connected to the outlet channel of the plug, and mufliing means in the tube.

5. A radiator vent comprising a shell hav ing a bottom inlet and a top neck, a plugseating in the neck and having an outlet channel and a valve seat therefor, a cap mounted on the neck, said cap having an out let and carrying a valve for the seat, said cap being adjustable on the neck to effect adjustment of the valve, and a bent tube in the shell connected to the outlet channel of the plug.

6. A radiator vent comprising ashell having a bottom inlet and a top neck, a plug seating in the neck and having a reduced portion, said plug also having an outlet channel and a valve seat therefor, a cap closing the neck, said cap having an outlet and carrying a valve for the seat, a bent tube connected to the reduced portion of the plug to open into the outlet channel, and a packing in the neck around the reduced portion of the plug.

In testimon whereof I aflix my signature 3 in presence 0 two Witnesses.
